Construction

Interdictor (YAGR-13) was laid down on 18 May 1945, under a Maritime Commission (MARCOM) contract, MC hull 3142, as the Liberty Ship Edwin H. Duff, by J.A. Jones Construction, Panama City, Florida. She was launched 29 June 1945; sponsored by Mrs. Edwin S. Duff; and delivered 27 July 1945, to the McCormack Steamship Co..[3][5]

Service history

She carried aircraft until entering the James River Reserve Fleet, Lee Hall, Virginia, 17 October 1945. Except for brief cargo service, she remained there until being acquired by the US Navy, 10 May 1957.[5]

She was converted to a radar picket ship at the Charleston Navy Yard, Charleston, South Carolina, and commissioned Interdictor (YAGR-13), 7 April 1958, Lieutenant Commander Joseph Palmer Dordahl, USNR, in command.[3][5]

Fitted with the latest and best electronic search and tracking equipment, Interdictor sailed 2 May 1958, for shakedown training in the Caribbean. She departed Charleston, 18 July 1958, and sailed to her new home port, San Francisco, California.[5]

Arriving 13 August, the ship assumed her role as an ocean radar station ship, part of America's vast early warning defense system. Operating with search aircraft, Interdictor could detect, track, and report enemy aircraft at great distances, supplementing land-based radar stations, and controlling high-speed interceptor aircraft in case of attack. She also carried out weather reporting duties during her three to four week cruises in the Pacific Ocean.[5]

Interdictor's hull classification was changed 28 September 1958, to AGR-13. She continued on radar picket patrols for the Continental Air Defense Command (CONAD) out of San Francisco, until decommissioned 5 August 1965.[5]

Decommissioning

Her name was struck from the Navy List 1 September 1965, when she transferred to the US Maritime Administration (MARAD) for lay-up in the Suisun Bay Reserve Fleet, Suisun Bay, California, where she remained until she was sold 13 June 1974. Her subsequent fate is not known.[3][5]
